The Washington Semantic Web Meetup

Meet local people interested in the Semantic Web, an initiative by the W3C [] to make the web "one giant database": The Data Web. We address technologies such as RDF, RDFS, OWL and applications that help to develop or that use ontologies, controlled vocabularies and rules systems in the enterprise and on the World Wide Web.

Events coming up

We don't have any upcoming events for this user group. Do you know this group? If so, why not submit a future event? We also support iCal, EventBrite and Meetup feeds.
